Hardware Specifications

C.2 ATM Network Modules

The LAN and WAN network modules are the physical ATM port interface cards that provide LAN/WAN connectivity to other ATM switches, ATM- compatible desktop computers and servers, hubs, routers, multiplexers, and carrier ATM services. Currently, network modules are available to provide ATM connections ranging from 1.5 Mbps to 622 Mbps over both fiber-optic and copper media.

This section details the technical specifications for each of the network mod- ules. All network modules are hot-swappable, reducing network and mainte- nance downtime. For complete information about hot-swapping network modules, please refer to Chapter 3, Hardware Maintenance Procedures, in this manual.
